Application October 10, 1942, Serial No. 461,582

1 Claim.

My invention relates to improvements in ship, or boat hulls of the Wooden type, the principal object in view being to provide for inexpensively and quickly constructing such hulls so as to be Watertight without calking the seams or resorting to similar procedure.

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are read with reference to the drawing accompanying and forming part of this specification.

In said drawing:

Figure 1 is a view in side elevation of a boat hull constructed in accordance with my invention,

Figure 2 is a View in longitudinal section taken on the line 2--2 of Figure 1 and drawn to an enlarged scale, and

Figure 3 is a View in transverse section, taken on the line 3-3 of Figure 2.

Referring to the drawing by numerals, my invention has been illustrated therein, by way of exemplification, as embodied in a boat hull I having the keel and prow beam 2.

According to my invention, the hull l is constructed of alternating planks 3 suitably secured to the frame, not shown, end to end with butt joints 4, and intervening, relatively narrower, planks 5 similarly secured end to end with butt joints 6. The planks 3 are of Wood suitably hard to provide for minimum expansion of the same when damp, or wet, whereas, the planks 5 are of a suitable relatively soft wood readily expansible when damp or wet.

By virtue of the described arrangement and character of the planks 3, 5, the latter expand under the influence of moisture against the harder and relatively rigid planks 3 so that waterproof joints are provided between the hard and soft planks obviating calking and similar procedure. The planks 3 may be of dry or moist lumber when applied as desired.

The butt joints 4, 6 are keyed together by dowel pins 1, of wood, driven into confronting grooves 8 provided in the abutting ends of the planks and extending from edge to edge of said planks, said dowel pins being socketed at their lower ends, as at 9, in subjacent planks and forming water stops as well as keys.

The foregoing will, it is believed, sufiice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What I claim is:

A boat hull comprising planks arranged with longitudinal edges abutting and with end butt joints to form alternate and intervening rows, and dowel pins fitted in and between the butt joints of the planks in each row coplanar with the planks and driven into planks in adjoining rows.

EUSTATHIS N. KLONARIS,
